Glowstone Smart Mug –Fine Bone China, 325 ml Dishwasher Safe, Self-Heating, wirelessly rechargeable, Hot Fully automatic Heated Ceramic Coffee and Tea cup, 1 hour battery

Self-heating mugs is a must in a working areas, especially when the environment is always cold.GLOWSTONE is a Nice fine bone china mug. It works.Good points:- nice design- fine bone china makes you feel the coffee taste- easy to clean- you can't control the temperatureCons:- you can't use it while charging. Once you put it on the charger it will stop heating.- you can't turn it on, it detects the hot liquids automagically. Sometimes it did sometime it didn't.- you can't use it to heat a cold drinks like Ember mug.- I found it hard to use it twice a day. Since it takes time to recharge. So you have only one shot per day.I used Ember before, it is great alternative but it won't last for more than 3 months before the taste changes and the steel is getting a weird scratches in the bottom. That's why I think the fine bone might be better in this.If you drink coffee one time perday go for GLOWSTONE. if you sometime bring coffee fromoutside and would like to have something that can heat even non hot drinks for you go for Ember.

I loved this mug and used it almost daily for 6 months until it stopped working. Of course the return window has long passed but when a coffee mug is this expensive, I expect it to hold up better.

Seems safer than a hot plate, had to return because it wouldn’t hold much coffee. If you like a half cup of coffee, this is the mug for you.

I think you’re either going to love this thing or not like it at all. It depends on your habits.For instance, this isn’t really a coffee mug, at least not in the U.S. It’s about 4 ounces too small for that. But it makes a dandy teacup. Or perhaps you’re a person who drinks smalls cups of coffee. In that case, this would be a better fit.It’s made from bone china. Perhaps this is important to you. Me, I’d drink coffee out of anything. My preferred cup is a stainless steel travel cup that keeps coffee warm for hours, holds 20 ounces, and costs $30. You don’t need to charge it, there’s no battery to wear out, and I still have a wallet full of crisp 20’s.But if you’re particular about appearances, this is a good looking little cup. It feels well made, and it looks like it fits into a nice place like a law office or board room. It also feels more like a traditional tea mug than those travel cups do.It does keep the liquid warm. It’s not “hot,” it’s lukewarm coffee, but it’s just on the lowest side of warm possible to not be a negative. Any colder, and I’d be complaining. Of course, ambient temperature will have an effect and it’s a little chilly in here right now. But in any event, you will never burn yourself on liquid that is kept warm in this cup.The charging base it comes with looks like a coaster, but it’s just a Qi wireless charging pad. It will charge your other wireless devices, and other wireless chargers seem to charge the cup. It’s not a coaster at all. If you place your cup on the charging pad, the cup will turn off because it cannot charge and heat at the same time. Does this sound ridiculous? It is. Since you can’t use the charging pad and the cup at the same time, I just keep the charging pad in the kitchen.So far I’ve sounded pretty negative, but this little cup is not meant for me. I don’t care if my coffee cup looks like a travel cup. If you want your coffee cup to be packed full of technology but resemble a small bone china coffee cup, this is what you need. It seems well made, and it works as expected. To be honest, the fact that it can’t charge and hold hot liquid at the same time is a bummer to me. Why not add that functionality, and make the charging pad an actual coaster? It’s such a no-brainer.This cup would have sharply disappointed me if I had spent $160 of my own money on it. However, as a gift, it would have delighted me, because I love little gadgets like this and I love coffee, so it’s a great combo. It’s just way too expensive to be a better option than a travel cup, at least for me.

Works okay, not what I was expecting especially for the price.

I've been using this mug for a week now for my morning pour-over.First, a few visual impressions. The base is rather heavy, seeing as it has the integrated (and sealed) heating element, battery and wireless charging receptacle built in. The rest of the mug is quite thin - about 1/8" walls - but it still feels sturdy and comfortable in the hand. The banding around the circumference and the cylindrical shape made my wife think of a soup can - no flowing curves here, instead a modern feel which I kinda like. I thought it looked a bit like an old-school Cylon when the red light illuminated, which it does to indicate heating. Personally, I like being reminded of old-school Cylons, so a win there.I'll say this for this mug - it really does work well. It senses the presence of hot liquid and turns on automatically to maintain about 150ºF (about what comes out of my pour-over setup), and lasts long enough for me to sip at my first cup of coffee in the morning for at least a half hour. The base and walls don't get appreciably warm - the base actually stays cool to the touch on the outside - but the coffee stays piping hot.The heavy base and thin walls make for a balanced, if base-heavy feel in the hand, which I find is very comfortable for sipping compared to the thicker-walled ceramic mugs I'm typically using. You're apparently able to put it in the dishwasher - up to 60ºC - but I haven't worked up the courage to do that.Charging seems to work fine. I leave the base on a shelf by my pour-over, and try to remember to put the mug back on it before I go to bed so that it's charged for the morning. The unit doesn't function while on the charging base, so there's no need to use it as a coaster by your desk unless that's where you store your mug.The only thing I wonder is if it's worth $160. That seems quite steep for something that keeps your coffee warm, but then again I'm firmly middle class when it comes to the cost of my coffee making setup. If you're the kind of person who spends four figures on your coffee, I suppose $160 wouldn't be too steep for a mug. For me - I have to say, I enjoy this mug, but if Amazon hadn't given it to me for free in exchange for this review, I probably wouldn't have bought it. Put it on my wishlist, sure.
